DDP 305-90 Remanufactured 90HP Injector Set (30% Over) – 2003-2004 5.9L Cummins

Unlock serious power from your 2003–2004 Dodge Ram 2500/3500 5.9L Common Rail Cummins with the Dynomite Diesel (DDP) 305-90 remanufactured injector set. These 30% over injectors deliver approximately +90 rear-wheel horsepower over stock and support up to 600–650 RWHP when paired with proper supporting modifications. They are widely regarded as the largest injector size recommended for a stock CP3 pump.

Each injector is remanufactured using brand-new OE-quality components, then precision flow-matched and balanced as a complete set of six. The result is consistent fuel delivery, a smooth idle, strong mid-range torque, and reliable performance for street driving, towing, and moderate performance builds.

Key Features

• 30% increased flow over stock for noticeable horsepower and torque gains
• Approximately +90 RWHP with supporting modifications
• Supports up to 600–650 RWHP (stock CP3 capable; more possible with an upgraded pump)
• SAC-style nozzles with patented dual-pilot hole technology (2 pilots at 0.005" + 6 holes)
• Improved atomization, reduced smoke, and better combustion efficiency
• Excellent street manners and drivability
• Remanufactured with new OE components to meet or exceed OEM standards
• Sold as a complete, balanced, and flow-matched set of 6 injectors

Fitment

2003–2004 Dodge Ram 2500 / 3500 with 5.9L Common Rail Cummins.

Important Notes

• Core charge applies (return your old injectors for credit).
• A pyrometer (EGT gauge) is recommended.

These injectors offer a proven combination of power, drivability, and durability—ideal if you want a significant upgrade without immediately replacing the stock CP3.
